Description
We selected the RCBS 18612 carbide three-die set as the cartridge-specific die station for the .44 Magnum Rifle Loading Room. It serves handloaders working with straight-wall .44 Magnum and .44 Special cases and keeps the core operations together in one matched set.
What the set does
The three-die system provides the cartridge-specific sizing, expanding and seating/roll-crimping operations needed to prepare and assemble .44 Magnum or .44 Special cartridges. The carbide sizing die reduces routine case-lubrication work while the roll-crimp seating die supports the firm crimp commonly used with revolver and tubular-magazine rifle ammunition.
Where it belongs in the loading sequence
This is the die station in a complete loading workflow: inspect and prepare the brass, size and expand according to the die instructions, choose a bullet suited to the firearm and intended work, consult current source-attributed load data, assemble carefully and evaluate the finished ammunition in the actual firearm.
